An elongate, rectangular box () and method for packaging containers (C), wherein the box can be cross-stacked for stable stacking of the boxes, and optimizes utilization of pallet space. Containers (C) are placed in the box in nested, offset relationship in a parallelogram shaped arrangement, and in one embodiment interior corner panels () extend angularly across two diagonally opposite corners of the box, defining an interior box shape closely conforming to the parallelogram-shaped arrangement of the containers. The corner panels may be cut from the side walls () and folded inwardly and secured at a free edge () to an adjacent end wall (), defining openings () in the side wall through which the containers are visible. Side wall segments () at the bottom and sides of the opening, in cooperation with the corner panels, retain the containers in place in the box. The box is especially suited for packaging four one-gallon containers.

Stackable shipping and display box

Carton partition unit

A ventilated grape box and a one-piece blank for forming it. The blank is formed from corrugated paperboard and is cut and scored to permit it to be folded into a stackable grape box without the need for fasteners. The upper edges of both ends of the box are provided with upstanding stacking tabs which are adapted to fit in complementary recesses in the lower edges of an identical box stacked above it. Each of two upper closure panels is provided with tabs which frictionally engage certain end panels to thereby maintain the upper closure panels closed after the box is filled with grapes. Certain end forming panels are folded to define a triangular column at each inside corner of the box, to thereby increase stacking strength.

Ventilated, stackable grape box

This invention is directed to an improved container made of corrugated paperboard or the like. Appropriately shaped slots in the bottom lock panels permit a fast-locking action without any binding as in conventional containers that are designed for interference fit.

Bottom speed lock for container

A one-piece paperboard partition and a die cut blank for forming it. The blank includes a rectangular panel made up of one set of two rectangular flaps or one or more sets of three rectangular flaps. The sets of flaps and the flaps in each set of the panel are arranged in a row and are foldably connected along one or more fold lines. Each set of flaps consists of one inner flap and one or two outer flaps. Each outer flap in a set includes a continuous slot, extending from the same side of its set of flaps and parallel to the fold lines. The blank also includes one or more bridging members, each of which is foldably connected to an inner flap, along the one slotted side of the set of flaps to which the bridging member is connected. The blank further includes one or more rectangular forked panels, each of which is foldably connected to the opposite side of a bridging member, remote from the one slotted side of the set of flaps to which the bridging member is attached. Each forked panel has one or more continuous slots extending from a side thereof, remote from the one slotted side of the adjacent set of flaps. The center line of a slot in each forked panel is colinear with a fold line between an inner flap and an outer flap. Also, the length of each bridging member, between an inner flap and a forked panel, equals the distance between the center line of the slot in an outer flap and the adjacent fold line between the inner flap and the outer flap. The panel, forked panels and bridging members are adapted to be folded, to form the partition, so that: the forked panels are transverse to the outer flaps; the flaps and forked panels are in an upstanding position; and the center line of the slot in each outer flap is vertical and colinear with a slot in a forked panel.
